Finding height given velocities

1. The problem statement, all variables and given/known data
A daredevil on a motorcycle leaves the end of a ramp with a speed of 39.0 m/s as in the figure below. If his speed is 36.7 m/s when he reaches the peak of the path, what is the maximum height in meters that he reaches? Ignore friction and air resistance.

When the daredevil reaches the top, his velocity is in the vertical direction is zero........ This means he can't go further up. Gravity will pull him down. Now, I suppose you can find the maximum height he reaches.
